This document introduces differentials in functions of several variables. It begins with a review of differentials in two variables using differentials dx and dy. It then extends the concept to functions of several variables, where the total differential dz is defined as the sum of its partial derivatives with respect to each variable times the differentials of those variables. Examples are provided to demonstrate calculating total differentials and comparing them to actual changes. The relationship between differentiability and continuity is also discussed.
The document provides advice and words of encouragement. It suggests that one should not compare themselves to others but instead focus on bettering themselves. It notes that while mistakes can be painful, over time the lessons learned from mistakes become experience that can lead to success. The document encourages accepting hardships and using them to become stronger and more valuable.
This document discusses partial derivatives of functions with multiple variables. It defines partial derivatives as derivatives of a function where all but one variable is held constant. For a function z=f(x,y), the partial derivatives with respect to x and y are defined. Higher order partial derivatives and partial derivatives of functions with more than two variables are also introduced. Examples are provided to demonstrate calculating first and second order partial derivatives.
The document provides advice for meeting different people from one's past. It suggests taking a positive approach by greeting old friends, lovers, enemies, and those who wronged you with a smile. It emphasizes appreciating people from your past as they helped you learn and grow, and shaped who you are, for better or worse. The document encourages making the most of opportunities to reconnect with past acquaintances and clarify misunderstandings.
Troubleshooting Complex Performance issues - Oracle SEG$ contentionTanel Poder

The document summarizes key points about web application security vulnerabilities and how to address them. It discusses common vulnerabilities like parameter manipulation, cross-site scripting, and SQL injection that occur due to improper validation of user input. It emphasizes the importance of validating all user input on the server-side to prevent attacks, and not storing sensitive values in cookies or hidden form fields that can be manipulated by attackers.

18. Observe autour de toi Et sois reconnaissant pour tout ce que tu as dans cette vie transitoire ...
19. Nous avons de la chance parce que nous avons beaucoup plus que ce dont nous avons besoin pour être heureux. Essayons de ne pas nourrir ce cycle perpétuel de consommation et d’immoralité dans lequel cette société “ moderne et avancée “ oublie et ignore les deux autres tiers de nos frères et soeurs
20. Envoie ce diaporama sans obligation ni attente d’une chance. Ne le garde pas, fais-le suivre et ce ne sera pas en vain
